source highlighter rouge is not working with asciidoctorj 2.0.0

[eiswind]

<sourceHighlighter>rouge</sourceHighlighter>
<attributes>
<rouge-css>style</rouge-css>

I tried with asciidoctor-revealjs 2.0.0 and revealjs 3.5.0 as suggested in the asciidoctor maven examples.

It renders as

<pre class="highlight listingblock"><code class="java language-java">

I expected rouge support to be working with revealjs.

This is plainly, because reveal.js itselfs only bundles monokai.css and zenburn.css.

You need to add new themews into reveal.js/lib/css/

Alternatively directly link to the CSS, i.e. like:

:highlightjs-theme: https://highlightjs.org/static/demo/styles/atom-one-light.css

I think we should support Rouge out-of-box. The syntax highlighting API changed in Asciidoctor 2.0.0 and we need to update the template accordingly:

Fixed by merging #287. Will be part of the next release.
